IMPROVEMENT IN Locus.

TO ALL WHOM IT MAY GONCERN:

Be it known that we, W. H. JAcKSON,.oi` Brooklyn, in the county of Kings, andl Statc'et- New Xork, and GEORGE MERRILL, of Newburyport, in-tl1e county of Essex, 'und State of Massachusetts, have invented and made n. certaiiinew and useful Improvement in Looms for Weaving; and we vdo hereby declare the following to --be a full, clear, and exact description ofthe snid invention, reference being had to the annexed drawing, makingl part of this specification, wherein- Figure 1 is a partial plan of our said loom.

Figure 2 is a. side elevationl of the same.

Figure 3 is an' elevation, transversely of the'loom, of the needle that 'carries the weft-thread and the parte connected tlie1ewith, and v Figure 4 is a section through the shuttle and its sustaining points.

Similar marks of reference denote the same part-s. v

Our invention lrelates t'o that class of looms in which ythe weft or filling-threadis carried by -a needle I through the shed, and interlocked by a shuttle-thread,returning to its normal position before the shed changes.

Instead of throwing a shu'ttle through the weft-thread when the needle is projectedfthrough the shed, we cause the .point of the needle vto passthroug'h the shed near the reeds, where itis wide,fand there is ample room for the needle, without risk of its point coming into eontaet'with the wurps, and then-give the needle a swinging movement, that passes its end aroundastanding shuttle or. bobbin, the needle returning through the shed or being drawn out near the point ort' weaving, so that the lay has-to Amove the weft-thread but a. short distance, und the selvedge on one side is formed by theinterloeking of the weft-thread with the/thread 'from vthe shuttle or bobbin.

-In the drawing, a represents the loom-frame j b, the yarnbeam' e, the whip-roller; d, the breast-roller; e, the cloth-roller and take-up, actuated by the ratcl1et-wheel e an'd ratchet e2, actuated from4 the main shaft z', in

nnyconvenient manner. v

gis the cam-shaft and cams, to work the foot-levers of the heddles t. the shaftg being actuated bythe pawl 7L to the wheel g-. Y

The parts thus far described may be of any usual character, construction, or size, and, as they form no part of our invention, are only in trodueed to illustrate the connection in which our-invention isemployed.

The reed le is set to swing o'n the axis2, and moved by a cam, 3, atthe proper time, and thrown back by the spring 23, or other device.

The weft-thread passes from a suitable cop,`bobbin, or spool, through the' eyes 4, 5, and 6, along the needle o, and through the eyes 7 and24 at its end, said end being bent downwards, as seen in fig. 3.

The needle o is carried by an arm, 8, from the slidel, that is set upon the lever m, and can be slid back and forth on lsaid levr fm.

This'lever m is connected at one end byu bolt, 9, that forms tsfulcrum. At' the other end a slot und pin or screw, seen 'oy'dotted lines in iig. 1, determine the amount of vibrating movement that may be given to that end of said lever by the link n, lever n', spring 10, vand com 11',.on the sha'ft z'. l

The slide l and needle o are reeiproeated upon the llever m, by the lever p, having its fulerum at 12, and connected by the link.13 to the slide Z.

q is a vertical shaft, with an arm, 1', linked by 'r' to the lever p, and this shaft q is partially-rotated by its pinion.14,acted upon by the rack s, that is reciproeated by 'a link, si, und eccentric s on the shaft t'. i

These parts'being properly timed, the ncedleo stands in the position shown in g. 1, when the shed is opened, the needl is then.l projected through theA shed, and its point passes beyond the shuttle x, and at this moment the cam- 11, moving thc lever n', link n, and lever m, causes the hooked point of the needle to"move across over ithe shuttle aj, as illustrated in Figure 5, drawing its weft-thread below such shuttle, and as the needle draws bachi the lling-thread draws from below and around such shuttle,'and is kept freni being pulled again out of the shed by i selvedgc shuttl'efthr-ead drawn* o.' n bobbn, 20, in the shuttle rv.

The lshuttle a: lies in a recessed uhuttle'hlolder., y, 'audit is formed to'r'eceive the movable bobbin 20, upon whichthread or yarn is wound the centre pipe oi' the bohbin forming the axis on which vthe bobbinrunwinds, as the thread 'is drawn off through holes inthe shuttle-case vthat producethe desired friction on the thread.

Wejprovide the reciprocating slidez with fingen-S21 and-22, and thisslide .e is moved by tho'link 22T, attached to the lever e', which latter is operated by a. cam on the shaft.-

.Atthetim e'thu.1; ,thel n eedle o passes 'over the shuttle, he fingers 21 22 areA raised so that the said needle passes between their ends, after which saidV fingers' are drawn dou'n,"the upper ngerientering the central holo of theehnittle, and the lower nger drawing out so as' to allow the tveft-'threatbtodrew out from below the llshuttle, and inV order torelieve the weft-thread from fi'ition between-the vishnttlfe and 'the' ed'geof the huttleholderym 'form the fingerl, so that in entering the hole in the shuttle, said shuttle `shell b'opressed back.' "Figa 5 illustrate'sthis feature, thefngers 21 and 22 being pointed, and. the finger 21 is Veet back from thb line of `the nger'2`2-.

:At the edge of the shuttle-holder is a'jnoteh forming` a hook, beneath which the thread from the shuttle draus' out totheselVedge.' This hookprevents 'this side of the s huttle being lifted by. the loop of weft-thread' passing below it, hence the shuttle rvill retain its position, and the weaving-operation be performed `ith certainty Y and reliability, as before mentioned.

'What we claim, and desire to secure by Letters Totem, is- 1.1 The mechanism, substantially suh as deseribedffor operating @weft-carrying needle, so that its-point -shell pass through `the wider part ofthe shed, and return near the point'of weaving,esubstantially as and for 'the purpose set forth. y

2. We laim a loom 'having a weft-carrying needle, arranged and operated substantially as describcd, so as to pass its eye through the shed obliquely, or 'near the beater, when tho latter isthro'wn back, then around a stationary hobbin, located at the opposite'edge of the shed, "and thence' back through the shed to the place of starting, subStantiall-ylas set forth, i

3. The combination of the shuttlegholder y, the reciprocating fingers 21 and 22, bobbin w, 4und the Wehlcarryingl needle, when eaidparts are constructed'and arranged for joint operationv with lthe mechanism of a loom, substantially as is herein described'. y

In Vwituees whereof, we have hereunto set our signatures, this tenth day of `Uetober, A.. D. y1867. i
